本発明は、可撓性包装容器の中に包装された感覚器官刺激特性が変化を受けやすい食品の感覚器官刺激特性の劣化を低減するまたは取り除く方法、およびその包装製品に関する。本発明は、また、スリップ剤として耐酸化性かつ非移行性ポリシロキサンを含むポリマーフィルムから作られた感覚器官刺激物質用可撓性包装容器に関する。ポリシロキサンスリップ剤の耐酸化性および非移行性は、中に包装された感覚器官刺激特性が変化を受けやすい食品（具体的には、（１）コーヒー、（２）ビール、（３）水、および（４）ワイン）と相互作用せずかつ前記食品に不活性な感覚器官刺激物質用可撓性包装容器を提供する。 The present invention relates to a method of reducing or eliminating deterioration of the organoleptic properties of a food product packaged in a flexible packaging container whose organoleptic properties are susceptible to change, and to a packaged product thereof. The invention also relates to flexible packaging containers for organoleptic substances made from polymeric films containing oxidation-resistant and non-migratory polysiloxanes as slip agents. The oxidation resistance and non-migratory properties of polysiloxane slip agents are important for the food products packaged therein whose organoleptic properties are susceptible to change (specifically, (1) coffee, (2) beer, (3) water, and (4) to provide a flexible packaging container for a organoleptic substance that does not interact with wine (wine) and is inert to said food.

No. 6,416,833, US Pat. No. 6,767,599. These patents describe polymer blends used to make flexible packaging for packaging, including food packaging. These patents are incorporated herein by reference.

食品包装分野において、包装の好影響すなわち付加的影響または包装の悪影響すなわちスカルピングは、望ましくない結果である。別の言い方をすれば、包装容器は包装される食品に不活性または中性であるべきであり、かつ相互作用しないものでなければならない。特に、ワインのような変質しやすい製品または水のような中性の製品については、包装によって引き起こされる風味プロフィールの変化は特に有害である。 In the food packaging field, the positive or additive effects of packaging or the negative effects of packaging, or scalping, are undesirable outcomes. In other words, the packaging container should be inert or neutral to, and non-interactive with, the food being packaged. In particular, for perishable products such as wine or neutral products such as water, changes in flavor profile caused by packaging are particularly detrimental.

可撓性液体包装容器のために、ある添加剤はこれらの包装を生産するのに必要なプラスチックフィルムの優れた加工性を提供する。フィルムの摩擦係数を低減する一般的な添加剤は、「スリップ剤」と呼ばれる。ポリエチレンフィルムのための典型的なスリップ剤は脂肪酸アミドを含む。脂肪酸アミドは、フィルムにあまり溶けず、フィルムの表面へ移動する。フィルムの表面における脂肪酸アミドのワックス層はフィルムの摩擦係数を低下させるように作用し、それによりその加工性を改善する。 For flexible liquid packaging containers, certain additives provide superior processability of the plastic films necessary to produce these packages. Common additives that reduce the coefficient of friction of films are called "slip agents." Typical slip agents for polyethylene films include fatty acid amides. Fatty acid amide is not very soluble in the film and migrates to the surface of the film. The wax layer of fatty acid amide on the surface of the film acts to lower the coefficient of friction of the film, thereby improving its processability.

しかし、これらの脂肪酸アミドの多くは、不飽和結合を含み、それは化学酸化を受けやすい。さらに、フィルム表面に存在しかつ液体製品と直接接触している脂肪酸アミドは、液体の中に移行する傾向を有する。液体製品の中に移行した酸化した脂肪酸アミドは、フィルムに接触する製品に悪臭を放つ場合がある。オゾンは脂肪酸アミドを酸化させるので、オゾン水のような殺菌用オゾンなどの酸化剤を使用する製品については、これは特に問題である。
本発明は、包装された食品の感覚器官刺激特性の劣化の上記の問題に取り組む。 However, many of these fatty acid amides contain unsaturated bonds, which are susceptible to chemical oxidation. Furthermore, fatty acid amides present on the film surface and in direct contact with the liquid product have a tendency to migrate into the liquid. Oxidized fatty acid amides that migrate into the liquid product can give off odors to products that come into contact with the film. This is a particular problem for products that use oxidizing agents, such as germicidal ozone, such as ozonated water, since ozone oxidizes fatty acid amides.
The present invention addresses the above-mentioned problem of deterioration of the organoleptic properties of packaged food products.

The slip agent used includes polysiloxane.

この明細書では、「感覚器官刺激特性の劣化の防止」、「感覚器官刺激特性の劣化の低減」および「感覚器官刺激特性の劣化の排除」という用語は、交換可能に使用される。 In this specification, the terms "prevention of deterioration of organoleptic stimulation properties", "reduction of deterioration of organoleptic stimulation properties" and "elimination of deterioration of organoleptic stimulation properties" are used interchangeably.

「バッグインボックス」またはＢｉＢとは、液体の貯蔵および輸送のための可撓性容器の一種を意味する。それは、段ボール箱の内部に収納された、通常数層のポリマーフィルムで作られた強いブラダー（またはプラスチックバッグ）からなる。バッグは充填会社に供給され、その後、充填会社は空のあらかじめ作られたバッグを充填するであろう。バッグに製品を充填する会社は、一般に、栓を外し、バッグを（例えばワインで）充填し、栓を元に戻し、その後、バッグを箱に入れる。バッグは、半自動機械用のシングルとして、またはバッグの間にミシン目があるウェブバッグとして入手可能である。これらは自動充填システムに使用され、バッグを自動的に充填する前または後のいずれかに、バッグはオンラインで切り離される。最終用途に応じて、栓の代わりにバッグに使用することができる多くのオプションがある。バッグは、冷蔵製品温度から８５℃までの温度で充填することができる。 "Bag-in-box" or BiB means a type of flexible container for the storage and transportation of liquids. It consists of a strong bladder (or plastic bag), usually made of several layers of polymer film, housed inside a cardboard box. The bags will be supplied to the filling company, which will then fill the empty pre-made bags. Companies that fill products into bags typically remove the stopper, fill the bag (eg, with wine), replace the stopper, and then place the bag in a box. The bags are available as singles for semi-automatic machines or as web bags with perforations between the bags. These are used in automatic filling systems, where the bags are disconnected online either before or after automatically filling the bags. There are many options that can be used in bags instead of closures, depending on the end use. The bags can be filled at temperatures from refrigerated product temperature up to 85°C.

バッグインボックス包装容器は、縦型製袋充填シールマシン（ＶＦＦＳマシン）技術を使用して作ることができ、その技術では、バッグはフィルムのリールからオンラインで製造され、その後ＦｌｅｘＴａｐが挿入され、その後一体型回転ヘッド充填機で充填される。 Bag-in-box packaging containers can be made using vertical form-fill-seal machine (VFFS machine) technology, in which bags are manufactured online from a reel of film, after which FlexTap is inserted and then Filled with an integrated rotating head filling machine.

ポリシロキサンスリップ剤
バッグインボックス容器のような本発明の感覚器官刺激物質用可撓性容器は、脂肪酸アミドとは対照的に、特にポリシロキサンスリップ剤を使用するポリマーフィルムから作られる。 Polysiloxane Slip Agents The flexible containers for organoleptic substances of the present invention, such as bag-in-box containers, are made from polymeric films that specifically use polysiloxane slip agents, as opposed to fatty acid amides.

シリコーンポリマーは化学的には非常に強く、食品包装で通常発生する状態下で酸化する傾向がほとんどまたはまったくない。したがって、それらは感覚器官刺激特性が変化を受けやすい食品に使用されるフィルムを改質するための理想的な候補である。 Silicone polymers are chemically very strong and have little or no tendency to oxidize under conditions normally encountered in food packaging. They are therefore ideal candidates for modifying films used in food products whose organoleptic properties are amenable to change.

一般的なスリップ剤を利用するフィルム配合物は、ワインや水のような変質しやすい製品に異味を加える傾向がある。低摩擦係数（ＣＯＦ）という長所を有するが、異味の欠点を有しないポリマーフィルム配合物から作成された可撓性容器を有することが非常に望ましい。さらに、他のスリップ剤は、感覚器官刺激特性が変化を受けやすい食品の中に移行する傾向を有する。食品を酸化し食品の中に移行するスリップ剤の傾向は、悪臭を放ちおよび／または感覚器官刺激特性が変化を受けやすい包装された食品の品質および味を低下させる可能性がある。シリコーンポリマー添加剤は、この問題の解決策を提供する。 Film formulations that utilize common slip agents tend to add off-taste to perishable products such as wine and water. It would be highly desirable to have a flexible container made from a polymeric film formulation that has the advantage of low coefficient of friction (COF) but does not have the disadvantage of off-taste. Additionally, other slip agents have a tendency to migrate into foods whose organoleptic properties are susceptible to change. The tendency of slip agents to oxidize and migrate into foods can reduce the quality and taste of packaged foods that are susceptible to malodor and/or altered organoleptic properties. Silicone polymer additives offer a solution to this problem.

スリップ剤としての脂肪酸アミドは、まさに、味と匂いの感覚器官刺激特性にこの問題を引き起こす。ポリエチレンフィルム用のスリップ剤として使用される脂肪酸アミドは、牛脂と植物の油のような天然資源からの脂肪酸のアミノ化によって作られている。例えば、よく知られたポリエチレン用スリップ剤は、エルカミド（ＣＡＳ １１２－８４－５）（１個の不飽和結合を有する２２炭素構造）である。ポリマー変性に使用される他の一般的なアミドは、ベヘンアミドとステアルアミドである。それらの対応する脂肪酸と同様に、これらのアミドは酸化を受けやすく、「悪臭のする」異味をもたらし、それは水やワインのような中性または変質しやすい内容物において特に顕著である。酸化は、フィルムの通常のエージングによって起こるかもしれないし、または充填の際に使用される酸化プロセス（例えばオゾン処理）の結果かもしれない。 Fatty acid amides as slip agents cause this problem precisely because of their taste and odor organoleptic properties. Fatty acid amides used as slip agents for polyethylene films are made by amination of fatty acids from natural sources such as beef tallow and vegetable oils. For example, a well known slip agent for polyethylene is Erucamide (CAS 112-84-5) (22 carbon structure with one unsaturated bond). Other common amides used for polymer modification are behenamide and stearamide. Like their fatty acid counterparts, these amides are susceptible to oxidation, resulting in a "stinky" off-taste, which is especially noticeable in neutral or perishable contents such as water or wine. Oxidation may occur due to normal aging of the film or may be the result of oxidation processes used during filling (eg ozonation).

ＳｉＯ単位の主鎖からなるシリコーンポリマーすなわちポリシロキサンは、酸化に対して非常に強い。ＰＥフィルムの表面摩擦を変更するための高分子量シロキサンポリマーは、より従来の脂肪酸アミドの問題を回避しながら、フィルムのＣＯＦを適切に低下させることができる。ポリシロキサンスリップ剤を含むフィルムで作られた可撓性容器の中に感覚器官刺激特性が変化を受けやすい食品（より具体的には、コーヒー、ビール、水およびワイン）を包装することは、包装される食品の感覚器官刺激特性を保持する。水はオゾン水を含む。 Silicone polymers, or polysiloxanes, consisting of a backbone of SiO units are very resistant to oxidation. High molecular weight siloxane polymers for modifying the surface friction of PE films can adequately lower the COF of the film while avoiding the problems of more traditional fatty acid amides. Packaging foods whose organoleptic properties are susceptible to change (more specifically, coffee, beer, water and wine) in flexible containers made of films containing polysiloxane slip agents is a Retains the organoleptic properties of food products. The water includes ozonated water.

ダウ・ケミカル社のＭＢ２５－３５のようなポリシロキサンスリップ剤の使用は、加工性が良く、丈夫で曲げ割れに強いバッグを実現し、しかし感覚器官刺激特性が変化を受けやすい食品への悪影響を回避することができるＰＥフィルムを提供する。酸化安定性に加えて、シロキサンの高い分子量は、それが製品の中に移行しないことを意味する。 The use of polysiloxane slip agents, such as Dow Chemical's MB25-35, provides bags that are easy to process, strong, and resistant to bending and cracking, but can have adverse effects on foods whose organoleptic properties are sensitive to changes. To provide a PE film that can be avoided. In addition to oxidative stability, siloxane's high molecular weight means it does not migrate into the product.
